Here in Chester County, we have started 2025 off as the 9th coldest January in the last 45 years. Only 2 days so far this year have featured above normal temperatures. Today and tomorrow could be the last above normal days through the end of this month. Some light rain tomorrow that could start as a bit of snow before the main snow event looks to arrive by late Sunday morning. The snow should stop by later Sunday evening. While it is snowing on Sunday temperatures will slowly fall during the afternoon into the teens by Sunday evening. During the day Monday temperatures will struggle to escape the mid to upper teens across the county. We will then see lows within a couple of degrees of zero both Tuesday and Wednesday morning.
